Hey Keith, I was wondering when you would jump in.
You should reference the 2 or 3 posts about this very topic since it was debated to death.
For my part, i'll refrain thank you very much....
There is no debate...it's plain and simple ...PSG is misrepresenting their product line.
I'm not the only one in the industry that believes that.Some that do not wish to be named due to conflict of interests.
Oh reference the other threads were personal attacks were made ...whatevere...the facts remains as I've stated....
John Dupree of the EPA said "Caddy is tested as a stove and is not listed as a furnace".
Your signature...PSG CADDY - High-Efficiency EPA Certified Wood & Pellet Burning Furnaces
to note the US EPA does not have a standard for furnaces..the NSPS is not law yet ...you also say it in a plural sence when only the little "Caddy" has been tested to the stove standard.
to repeat...a STOVE STANDARD...why are not all of the PSG furnaces EPA Listed? The boxes are too big...John Dupree admitted trying to test a large firebox to the stove standard would be futile...there's no way that the emissions could become acceptable.
That is the reason for the New Source Performance Standard for furnaces. It is there to give them a fair shake...those small stoves have low grams per hour...adding 3-5 times the wood mass in a much larger firebox needs a different set of rules or protocols hence the new testing protocols which are being hammered out.
They knew it was unfair 20 years ago when the EPA 1st came out with the EPA 40/60 rule Subpart AAA for stoves...hence furnaces were exempted.
To advertise as being EPA certified when there is no EPA test for "FURNACES" is lying.
It'll take some looking but I'm gonna go find that recording and make a link for everyone to hear.
